+description: Attach code symbols with LSP integration.
+---
+
+Implement Symbol Attachments
+
+---
+
+### LSP Integration
+
+Integrate with the Language Server Protocol (LSP) to get a list of symbols in the current project.
+
+---
+
+### @ Symbol Autocomplete
+
+When a user types `@` followed by a symbol-like pattern, trigger an autocomplete with relevant code symbols.
+
+Include symbols from various file types supported by LSP.
+
+---
+
+### Attach and Navigate Symbols
+
+Allow users to select a symbol from the autocomplete list to attach it to the prompt.
+
+Display attached symbols as interactive chips. Optionally, implement functionality to jump to the symbol definition in an editor.
+
+---
+
+### Acceptance Criteria
+
+- Typing `@` followed by a partial symbol name displays matching symbol suggestions.
+- Selecting a symbol creates an attachment chip.
+- Attached symbols are correctly formatted for submission.
+- (Optional) Clicking a symbol chip navigates to its definition.
